Hadith.1889 - In the narration of al-Mufaddal ibn Umar from Abu Abdullah (as) regarding a man who had relations with his wife while both were fasting, Imam (as) said:
"If he forced her, he must bear two expiations. If she consented, then he must bear one expiation and she must bear one expiation. If he forced her, he is to be lashed fifty times, half the prescribed punishment. If she consented, he is to be lashed twenty-five times, and she is to be lashed twenty-five times as well."
